CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 292,557, dated January 29, 1884. I Application filed June 12, 1883. (No model.) I

' To all whom it may concern.-

tached to them, coupled.

coupling that can beoperated without going between the cars when they are to be coupled,

thereby saving the loss of life and limb and doing it quicker, thereby saving time and 1abor; also saving the loss of coupling-pins.

The invention consists in the peculiar construction and operation of the cam A, which is placed in the draw-head D, back of the coupling-pin C, and held in place and operated by the spring B, as shown in Figs. 1 and 2. It

has a projection near its center, which rests on the top of the link E and holds it up in a horizontal position in one of the draw-heads,

as shown in Fig. 2, left side; also another projection near the top, which fits into a slot in the end of the pin G, as shown in Fig. 2, right side. When drawn up, the last-named projection prevents the pin from being drawn out and lost. It also holds the pin up in a perpendicularsituation,leaving thedraw-headopento receive the link when the cars are to be coupled. It is held in its place and operated by spring B, as shown in Figs. 1 and 2. It'is coupled by simply pushing the cars together, when the link E enters the draw-head D, strikes the cam A, pushing it back and relieving the pin G, allowing it to drop down through the link E and draw-head D, thereby coupling the cars without the aid of the hand or anything else to hold it up, thereby making it a self-coupling.

What I claim as my invention is- The arrangement of a cam, A, having two proj ections, as shown, working in combination with a slotted pin, 0, in the draw-head D, in the manner set forth.
